I had an idea sparked by my girlfriends truck getting broke into the other day. They broke the window popped the hood and had someone cut the posative battery cables going to the battery so the alarm would not go off when they opened the door. My questioin is could i put some sort of additional power source like a battery hidden in the trunk powering the alarm so if they cut the wires under the hood it wont kill the alarm? If this would work anyone have any ideas on how to make this happen? What wires would need to be run and where would they be connected to? Remember this is just some crazy idea i've come up with please let me know if its been done before or can be done.

Thanks

 

Yup. It's called an alarm backup battery.

 

dei part number 520T.
I have had one in every car I have ahd an alarm on. one of the best add ons available (if not the best).

 

Awsome! I didnt think i was the only one to come up with this idea. Anyone know where i can find one and what would be the best aftermarket alarm out there (with shock sensors and all that good stuff)...the whole incident has me nervouse about my civic

 

got a couple, just give me a call. gl
